[Objectives] To study the expression of Med 19 protein in tongue cancer and its significance. [Methods] Immunohistochemical method was used to detect the expression of Med 19 protein in tongue cancer tissue and paracancerous tissue. [Results]The expression of Med19 protein in tongue cancer tissue was higher than paracancerous tissue and normal tissue. The expression of Med 19 protein was related to the tumor lymph node metastasis. However,there was no significant difference in sex,age,Tumor Node Metastasis( TNM),and differentiation degree. [Conclusions] Med 19 protein participates in incidence and development of tongue cancer and may become diagnostic indicator and therapeutic target for tongue cancer.
